IRON FOLDING BEDSTEAD.

srnoIFIcAirIoN forming part of Letters Patent No. 637,146, dated November 14, 1899.

Application filed February 18,1899. Serial No. 705,975 (N0 model-l To all whom-it may concern.-

Be it known that I, JAMES MONTGOMERY, a citizen of the United States, residing at Chi- 'cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Iron Folding Bedsteads, which are fully set forth in the following specification, reference being had to the ac companying drawings, forming a part hereof, and in which-' Figure 1 shows my said iron folding bedstead in side elevation in open position. Fig. 2 shows the same when folded. Fig. 3 shows the mechanism which actuates the canopy. Fig. 4 shows an enlarged view of the jointed post of the foot-end legs, together with fragments of the parts which actuate said legs. Fig. 5 shows the legs of Fig. 4 turned quarter-way around, with fragments of the mechanism which actuates said legs. Fig. 6 shows the head end of the bedstead, with the canopy in its upper position shown in broken lines. Fig. 7 shows in plan one side rail and a fragment of a fabric or wire mattress. Fig. 8 shows a side view of the joint of the side rail. Fig. 9 shows a plan view of the joint of the side rail.

Like letters of reference denote like parts of the figures.

The object of my invention is to provide an iron folding bedstead provided with a wovenwire mattress. To attain said desirable end, I construct my new bedstead in substantially the following way, namely:

The tubular posts ahave the usual T-shaped pipe-fixtures a, into which are screwed pipepieces (1, into which slide pipes or rods 6, secured in elbows f, provided withlegsf which are connected bya cross-rod j. Inside of said parts 01 e f is the side rail 1), pivoted at f to the elbow f and hinge-jointed at Z and 0 between the parts I and f. The foot-end posts have their T-shaped fixtures a", to which the rails 12 are attached. Said fixtures have each a hole 9, into which slip the upper ends of the legs 72., which are provided with slots h, through which passes a pint in the lower end of said hole, the inner sideof said fixtures being cut away, as seen in Fig. 4, to allow said legs to turn on the pin 1 to the position shown in Fig. 2. To the transverse connecting-rods j j is atttached a bar or rod lo, and

to the inner rod e or any of the moving parts f f f is attached a cord at, passing under the pin Z, thence up through the post a and out over a pulley 0 near the top of said post, and to a canopy m, hinged at m to either a pin in each post or a rod m connecting the posts at.

Cross-bars t, connected to the side bars 19, hold the woven-wire fabric 10, and a rodp near the joint 0, held by the side rails either over or in the fabric w, holds the fabricdown and from stretching directly from the bars t to i, so as'to enable a single person to extend the bedstead, otherwise impossible when the Web reached directly from bar to bar t, as such tension would raise the head end of the bedstead. In Figs. 8 and 9, 0 shows another and preferred form of hinge.

The web w must have a certain amount of tension to make it useful, which is attained by my hinge-jointed and pivoted side rails fulcrumed so as to form a toggle-joint of great power.

- The bedstead is folded by raising the foot end, which depresses and opens the joints at the hinges c and brings the upper end of the slot h on the pin Said action also shortens the space between the parts a and f which draws on the rod lo and brings the legs h inward parallel to the bars I). Said inward motion of the legs f slackens the cord at, and thus allows the canopy to move from its elevated position (shown in broken lines) to the position shown in full lines in Figs. 2 and 3. Said canopy is here shown as a wire or rod to hold a curtain or curtains; but it may be of any other suitable material and form.

In unfolding the bedstead the rod 19 holds the fabric near to or below the hinge at c, and thus pulls in such a manner through the agency of said rod 19 as will stretch the fabric to without tilting up the head end of the bed stead and give said fabric its necessary tension by the work of a single person, an act which would fail and cause the head end to rise in the air if said rod 19 or a similar de vice wereomitted.

By unfolding the bedstead the above-described actions of the several parts will be reversed and assume the position shown in Fig. 1.

I have shown elastic woven-wire fabric connected to my side rails, which works in con nection With my intermediately-hinged side rails and makes a very simple and desirable structure; but it is not essential to have said Web, as the said Web may be replaced by any other suitable spring-bottom without interfering with the operation of the canopy or the mechanism that operates it or with the folding of the bedstead.

What I claim is 1. The combination with head and foot ends and intermediately-hinged side rails pivoted to said ends, of reciprocable supports pivoted to said rails, intermediate said ends, and means to hold said intermediate supports erect, substantially as specified.

2. The combination with the head and foot ends and intermediately-hinged side rails con-
